Traumatic Brain Injuries (TBI) vs. Acquired Brain Injuries (ABI)

Home > Brain Injury > Differences Between Traumatic Brain Injuries (TBI) and Acquired Brain Injuries (ABI)

We at BrainBeHappy.com have done much research into what is deciphered as the definition of Traumatic Brain injury vs. Acquired Brain Injury and have adopted what www.braininjurynetwork.org has adopted. They have done extensive research into this matter and if you want to see their findings see http://www.braininjurynetwork.org/thesurvivorsviewpoint/definitionofabiandtbi.html for a detailed explanation on this matter. But as it stands, these are the definitions we have adopted:

DEFINITION OF TRAUMATIC BRAIN INJURY (TBI):

A traumatically induced structural injury and/or physiological disruption of brain function as a result of an external force that is indicated by new onset or worsening of at least one of the following clinical signs, immediately following the event:

  • Any period of loss of or a decreased level of consciousness;
  • Any loss of memory for events immediately before or after the injury;
  • Any alternation in mental state at the time of the injury (confusion, disorientation, slowed thinking, etc.);
  • Neurological deficits (weakness, loss of balance, change in vision, praxis, paresis/plegia, sensory loss, aphasia, etc.) that may or may not be transient;
  • Intracranial lesion.
  • External forces may include any of the following events: the head being struck by an object, the head striking an object, the brain undergoing an acceleration/deceleration movement without direct external trauma to the head, a foreign body penetrating the brain, forces generated from events such as a blast or explosion, or other force yet to be defined.

1.7 million people sustain a traumatic brain injury (TBI) each year. According to the Centers for Disease Control and Injury Prevention, the leading causes of TBI are:

  • Falls (35.2%)
  • Motor vehicle-traffic crashes (17.3%)
  • Struck by/against events (16.5%)
  • Assaults (10%)

DEFINITION OF ACQUIRED BRAIN INJURY (ABI):

An acquired brain injury is an injury to the brain that has occurred after birth, but is not related to congenital defect or degenerative disease. Causes of ABI include (but are not limited to) hypoxia, illness, infection, stroke, substance abuse, toxic exposure, and tumor. ABI may cause temporary or permanent impairment in such areas as cognitive, emotional, metabolic, motor, perceptual motor and/or sensory brain function.
